Ultimate Airsoft AEG Gearbox Mil-Spec Springs

Ultimate Airsoft Gearbox Upgrade Spring

Ultimate Mil-Spec AEG springs are manufactured out of the best steel (SiCr) available for springs. With minimum loss in power and consistency, the Mil-Spec spring series is the ULTIMATE choice for your AEG. The Mil-Spec springs are colour coded for better identifying them when switching out the spring for different skirmishes.

The springs are designed from the start to deliver the best output while keeping it's coil strength, consistency and quality. With the closed and grinded ends, the spring remains in place during use to prevent reduction in ROF due to bending.
